Worst bank ever

Fnb had really inconvenience me, worse on a day I needed the money the most stuck and needed to get my car towed at night unsafe. Fnb allowed sla service provider to debit my account 10 days before the agreed debit order date as per the debit order mandate accepted through the debit order date. Worse when I ask fnb to reverse the amount I am told the service provider blocked the reversal and I must contact the service provider myself and their debit reversal debit will keep in touch to explain more however their system is down and can only talk to me after 2am. 1. Fnb is failing us, how can it allow a service provider to debit an account before the duly accepted date as per the debit order mandate accepted through their app. 2. How can fnb allow service providers to inconvenience us by getting through our accounts without our permission. I accepted a debit order for a specific date, how can fnb open a platform for the service providers to do as they please. 3. What is the purpose of accepting debit order mandates through the fnb app if fnb is not going to protect its clients. 4. A whole reversal department offline for more that 6 hours. 5. A whole fnb being over powered by service providers, can reverse amounts which where ********ly debited. 6. Why are we paying bank/service fees.

Can we please be taken seriously this is totally unacceptable.
